造林密度对单位面积木材产量和质量均有很大影响,只有密度适宜,才能保证林木持续的速生,在较短的时期内获得较好的材种和较多的材积。所以,研究合理的造林密度,正确地调节好林分个体和群体的生长关系,是营造速生丰产林的重要环节。 Afforestation density has great influence on the yield and quality of wood per unit area. Only when the density is suitable, can the continuous rapid growth of trees be ensured, and better timber species and more volume can be obtained in a short time. Therefore, to study reasonable planting density and correctly adjust the growth relationship between individuals and groups of stands is an important part of creating fast-growing and high-yielding forests.
